It gave an interesting reveal on Nora Clavicle's secret origins, and promised an entwined "League of Shadows" adventure with Bane, Puzzler, Lola Lasagna, Ra's Al Ghul, Cabala... but made Dr Cassandra into an African American.

Would love to see fanfic that features all three Catwomen (not counting the recent animated feature).

When the second animated movie ("Batman vs Two-Face") came out, I assumed it would be a sequel to the first one, but it happens much earlier, with an opening montage establishing a series of Two-Face altercations over months/years. Black cat Hecate, name dropped in the "Batman '66" movie, appears - and then there's the switcheroo between Newmar and Meriwether, which seemingly places it just before the "Batman '66" movie.

The crossover comic mini-series with "Wonder Woman" does an interesting job with the three Catwomen. It opens with Eartha's version, then Lee's (adding a tail to the costume) turns up, then Julie's. No explanations are given, although they are working with Ra's Al Ghul, so I was expecting a connection with the Lazarus Pit might be established. But it seems that the writers leave it up to readers to make their own interpretations.

Another theory?
When Tut discovers Bruce Wayne is Batman in I'll Be a Mummy's Uncle he receives a blow to the head, becomes McElroy again and forgets. But what if he becomes Tut again? Surely he will remember?
After all, he did spot the blow up Batman mannequin in the cabinet
